Choose the description that matches the inequality p > -3.
A line traveling to the right with a closed dot on p = -3.
A line traveling to the left with an open dot on p = -3.
A line traveling to the left with a closed dot on p = -3.
A line traveling to the right with an open dot on p = -3.
Answer:
The correct option is: A line traveling to the right with an open dot on p = -3.
Option D is correct option.
Step-by-step explanation:
Choose the description that matches the inequality [tex]p > -3[/tex].
The inequality states that, the value of p is greater than -3
For drawing the number line for the inequality, we know that if p > -3, there will be open circle on -3 because -3 is not included and the greater values are on the right side of number line, so line will be travelling to right side.
The number line is attached in figure.
So, The correct option is: A line traveling to the right with an open dot on p = -3.
Option D is correct option.

Write the equation of a line parallel to the line y = 2x that passes through -2,-1
Answer:
y = 2x + 3
Step-by-step explanation:
A line parallel to y = 2x has exactly the same slope but a different y-intercept, b.
Start with y = mx + b, and replace m with 2, y with -1 and x with -2:
-1 = 2(-2) + b, or
-1 = -4 + b.
Then b = 3, and the desired equation is y = 2x + 3
Simplify the expression,
3x + 2x + x =

An apple tree measures 20 1/2 feet tal,over the next five years,it grew to the height of 28 feet. What was the average yearly growth of the apple tree
Answer:
6.4%
Step-by-step explanation:
We solve this question in using the population growth rate formula
P(t) = Po(1 + r)^t
P(t) = Population after t years = 28 ft
Po = Initial Population = 20 1/2 feet or 20.5 feet
r = Growth rate = ?
t = Time in years = 5
Hence:
28 = 20.5 (1 + r)⁵
Divide both side by 20.5
28/20.5 = 20.5 (1 + r)⁵/20.5
1.3658536585 = (1 + r)⁵
5th root both sides.
5√(1.3658536585) = 5√(1 + r)⁵
1.0643411027 = 1 + r
r = 1.0643411027 - 1
r = 0.0643411027
Converting to percentage
r = 0.0643411027 × 100
r = 6.43411027%
Approximately = 6.4%
The yearly growth rate of the apple tree = 6.4%
The Smiths spend 6% of their budget on entertainment. Their total budget this year is $2,000 more than last year, and this year they plan to spend $2,760 on entertainment. What was their total budget last year? Their total budget last year was?
Answer: Their total budget last year was $44,000.
Step-by-step explanation:
Given: Smiths spend 6% of their budget on entertainment.
Total budget this year = $ 2000 more than last year.
Let x = Budget for this year.
Money on entertainment = 0.06x = 2760
[tex]\Rightarrow\ x=\dfrac{2760}{0.06}= \$46,000[/tex]
⇒ Budget for this year = $ 46,000
Budget for last year = $ 46,000 - $2,000 = $44,000
Hence, their total budget last year was $44,000.

Flagship Cinemas sells movie tickets that are $4 for matinees and $7 for regular shows. One night the theater sells 578 tickets and collects $3365 in total ticket sales. Whích system best represents the situation?
Answer:
4x + 7y = 3365
x + y = 578
x = matinees
y = regular
Step-by-step explanation:
Given
$4 = matinees
$7 = regular
Total tickets = 578
Money collected = $3365
If one calls the amount of matinees that when "x" and the amount of regulars that went "y", then one can form the system;
4x + 7y = 3365
x + y = 578
Solving the system;
Multiply the second equation by (-4)
4x + 7y = 3365
-4x - 4y = -2312
Add the equations
4x + 7y = 3365
-4x -4y = -2312
3y = 1053
Inverse operations
3y = 1053
/3 /3
y = 351
x = 227

Mr. Bennett purchased a condo several years ago at a selling price of $329,550. Recently he had the condo appraised and it is now worth $184,548. By what percent did the value of the condo go down?
Answer:
44%
Step-by-step explanation:
Given that,
Initial price = $329,550.
Final price = $184,548
We need to find by what percent the value of the condo go down. The percent decrease or increase is givnen by the formula as follows :
[tex]\%=\dfrac{\text{change in value}}{\text{initial value}}\times 100\\\\=\dfrac{329,550-184,548}{329,550}\times 100\\\\=44\%[/tex]
So, the value go down by 44%.

An electronics store keeps track of the number of computers sold. Last month, 30% of the computers were notebooks. If the store sold 390 notebooks last month, what was the total number of computers sold in the same month?
1,300 computers
1,560 computers
975 computers
1,114 computers
Answer:
1,300 computers
Step-by-step explanation:
As, they are saying they sold 30% of the computers last month
And that 30% was 390
So, x = the total number of computers
30% of x = 390
30% = 30/100 and "of" represents multiplication
So 30/100 X x = 390
We will transpose everything
30x = 39000
x = 39000 ÷ 30 = 1,300
So 1,300 computers were sold

105 people are going to a movie 6 people can ride in each car how many cars are needed to get all 105 people to the movie
Answer:
17.5
105 divided by 6 equals 17.5
18 cars are needed to get all 105 people to the movie.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, 105 people are going to a movie 6 people can ride in each car.
Let the number of cars required be x.
Now, x= Total number of people/Number of people in each car
= 105/6
= 17.5
≈ 18
Therefore, 18 cars are needed to get all 105 people to the movie.
